Abstract

En construisant un nouveau balcon sur l'exterieur du plateau d'un balcon existant (1), on utilise un procede simplifie par rapport au procede de reparation connu jusqu'a present. Le procede connu mentionne consiste en un travail de reparation des parties endommagees, mais le procede est tres fastidieux et par consequent extremement couteux a executer. De plus, un balcon repare de cette maniere doit etre controle de temps a autre. En premier lieu, deux unites laterales (4, 5) sont fixees sur l'unite (16) des deux cotes d'une plaque ou dalle de balcon existante (1). A ces unites laterales (4, 5), une unite de bordure laterale (9) est boulonnee. Cette structure forme le pignon du balcon. En dernier lieu, dans la partie frontale du balcon, une unite de bordure laterale (9) et une unite frontale (6) sont montees entre les unites (4, 9) du pignon. Dans son fond, l'unite laterale possede un rebord sur lequel la plaque de fond (10) avec des nervures de renforcement (3) peut etre montee. Au-dessus, est place une plaque de couverture (11) qui constitue l'unite de couverture. Ulterieurement, toutes les cavites (12) du balcon sont bouchees, p.ex. avec des mousses de polyurethane.When building a new balcony on the outside of the shelf of an existing balcony (1), a simplified process is used compared to the repair process known up to now. The known process mentioned consists of repairing the damaged parts, but the process is very tedious and therefore extremely expensive to carry out. In addition, a balcony repaired in this way should be checked from time to time. Firstly, two lateral units (4, 5) are fixed on the unit (16) on the two sides of an existing balcony plate or slab (1). To these side units (4, 5), a side edge unit (9) is bolted. This structure forms the gable of the balcony. Finally, in the front part of the balcony, a side edge unit (9) and a front unit (6) are mounted between the units (4, 9) of the gable. At its bottom, the side unit has a flange on which the bottom plate (10) with reinforcing ribs (3) can be mounted. Above is placed a cover plate (11) which constitutes the cover unit. Subsequently, all the cavities (12) of the balcony are blocked, eg with polyurethane foams.

Description

A METHOD AND A MEANS FOR CONSTRUCTING A BALCONY.

This invention relates to a method for constructing a balcony and a means for executing the method.

Hitherto known balcony constructions have mostly been based on reinforcing iron which projects from the wall and is casted round with concrete for the form¬ ation of a balcony plate.

Balconies of the prior mentioned art have in some cases turned out to be highly dangerous, since the concrete and the reinforcing iron can be demolished due to the weather. For instance pop-outs of the con¬ crete over the reinforcements or formation of cracks in the concrete can occur. The carrying capacity of the balcony plate will consequently be reduced and this will result in a falling down of the balcony.

Corroded balconies have so far been repaired by cut¬ ting off or by removing bad concrete, or they have been demolished. The mentioned repair work depends on a sufficient strength of the reinforcing iron in order to carry out a satisfactory repair of the concrete slab. The repair work can amount to app. dkr. 30.000,- in materials and cost of labour. In case a balcony cannot be repaired in this way, it must, as already mentioned above, be removed and re¬ placed by a new one. However, such balconies must be checked at intervals, e.g. every five years.

This is an expensive as well as a troublesome way of repairing. It is the object of the present invention to provide an improvement of these defects by con¬ structing new and replacing old corroded and dange-

OMPI /.. IPO - rous balconies, and this is achieved by using a me¬ thod according to which two outriggers are fastened to the construction whereafter an edge unit is fast¬ ened to the sides facing each other of the outrig- gers, whereafter another edge unit is mounted be¬ tween the mentioned units in such a way that a cover plate and a bottom plate can be fastened to the upper respectively to the lower edges of the edge units. By applying the mentioned method it is possible to construct a balcony around a possibly already exis¬ ting balcony and without letting this already exis¬ ting balcony constitute a carrying part of the con¬ struction. Furthermore the hitherto known defects are quite removed by constructing the new balcony in this way, since it can be made free of maintenance by an adequate choice of materials. The fact is that con¬ crete does not form part of the construction. The balcony can be constructed of prefabricated sections which simplifies and reduces the price of the prod- uction.

By filling up the whole cavity of the balcony, as referred to in claim 2, with e.g. foamed pclyurethan, accumulations of water are avoided and an expedient sound absorption is achieved.

By using steel sections preferably of stainless steel, as a carrying unit at the sides and enclose these in a closed section, e.g. of aluminium, as referred to i claim 3, a reliable carrying construc icn free of maintenance is achieved.

By providing the edge units mounted along the sides with a groove, as referred to in claim , a buil -

OM?I IPO ,in drain for rainwater, which can be connected with the drainpipe system, if desired, is achieved.

Finally it is adequate, as referred to in claim _S to provide the bottom plate with inside ribs to make the plate sufficiently stiff and stable of shape.

The invention will now be elucidated further in de¬ tail with reference to the drawing in which

Fig. 1 shows a section through a balcony taken along the line I-I in Fig. 2,

Fig. 2 shows a partial section through the bal- cony taken along the line II-II in Fig.

Fig. 3 shows a sectional view of the side gable of the balcony, and

Fig, 4 shows a sectional view of the front of the balcony.

In Fig. 1 and 2 an embodiment of a balcony is shown, which is constructed according to the method of the present application and with an already existing bal¬ cony plate 1 enclosed in the balcony.

Before constructing the balcony, old rails and simi- lar things must be removed from the old balcony plate.

Subsequently side units 4 are fastened to the con¬ struction 16 in any adequate way. They can be fast- ened to the walling e.g. by a screwing on with rust¬ proof bolts, a fastening to the steel pilaster strip in the horizontal division of the construction, or they can be suspended between pillars at the outside of the construction. The mentioned side units are shown on an enlarged scale in Fig. 3- They are con¬ stituted by U-shaped stainless steel sections 5, the projected length of which correspond to the length of the balcony. When the U-sections 5 have been fast- ened, a closed section 4 is inserted to enclose the mentioned sections. The closed section can adequate¬ ly be made of aluminium.

The side edge unit 9 is fastened to the two mentioned side units 4, 5 by means of rustproof bolts. The side edge units are also adequately made of aluminium with the shown cross sectional shape.

Between the ends of the side edge units 9 of the gables another side edge unit 9 is mounted, which runs along the front of the balcony as shown in Fig. 1 and 4.

The side edge unit can be assembled by means of fitted connecting angles 7 and fish-bolts 8, which are pre¬ ferably made of stainless steel.

A front unit 6 is also screwed on to the front-side edge unit 9, as shown in Fig. 4.

At the bottom of the balcony a bottom plate 10 is placed, which at convenient intervals is provided with ribs 3 riveted on in-order to stiffen the plate. Plates and ribs are also made of aluminium. The bottom plate is placed in such a way that it rests at the bottom flange of the side edge units and is fastened to this in an adequate way.

Likewise a cover plate 11 is placed at the top side of the units, as shown in the figure. The plate 11 can be of any adequate type.

Subsequently the cavity 12 between the side edge units, the bottom plate and the cover plate is filled up with a fitted material, e.g. foamed polyurethan, so that free air-filled spaces within the balcony will not occur.

The balcony plate having been built up the railing can be mounted, as shown in Fig. 1 and 2. The railing is at the bottom fastened at the side units 4, 6 and in a fitted way to the construction.

As it appears from this description the balcony can be built^' up on the outside of an already existing bal¬ cony plate.

The method simplifies the construction of balconies considerably, since there will hardly be any incon¬ veniences for the inmates involved, as the mounting takes place from the outside without intervention in the appartment. By applying a mobile lift two men can build the balcony.

The method described above can be modified in dif- frent ways, as large or small parts of the balcony can be prefabricated. The bottom plate can for in¬ stance be inserted in between the side units of the

OMPI /., V/IFO _A* gable , and the angle plate 2 can thereafter be fast¬ ened to the walling. Subsequently the front can be mounted.
